Lips locked at all times — including for bathroom breaks and meals — is the less than romantic challenge facing Thai couples trying for the kiss to blow away all kisses at a Valentine's Day marathon.
Seven couples have brought their lips together in the Thai beach resort of Pattaya, some 62 miles southeast of Bangkok, hoping to break the world record for longest continuous kiss, which currently stands at nearly two days. The marathon kicked off on Sunday and will go through Valentine's Day, with prizes and glory for the pair that manages to hold out longer than 46 hours, 24 minutes and nine seconds.
